Product Description

 

KYN28-12 Metal-clad Withdrawable Enclosed switchgear power cubicles

distribution switchboard air insulated type switchge 
 Product overview

 

KYN28 indoor metal-clad withdrawable switchgear(hereinafter short as switchgear) which is

for distributing and accepting 3-phase AC electricity (3-12 kV, 50 Hz) distribution system,

single-bus and single-bus sectionalized system. It is universally applied within power

transmission of middle/small generators in power plants; power receiving, transmission for

substations in power distribution and power system of factories, mines and enterprises, and

starting of large high-voltage motor, etc. The switchgear compliant with IEC298,GB3906-9.

Besides, it also can control, protect and monitor the circuit.
Simple and effective lock system to prevent misuse. Reliable FIVE-PREVENTION interlock

can effectively prevent from mal-operation and entrance into energized compartments.
1, Prevent pushing and pulling circuit breaker handcart with loads;

2, Prevent circuit breakers from mal-operation;

3, Prevent the circuit breaker from closing and connecting when earth switch in live condition;

4, Prevent straying into electrified compartment;

5, prevent connecting error of grounding switch while live.
